MACHINE FOR MAKING COlLED-WIRE FABRIC,

STEGIFIUATIGN foriningpart of Letters Patent No. 688,843, dated December17, 1981.

Application filed August 28,1901.

To all whom it may concern.-

Be it known that I, JOHN F. GAIL, a citizen of the United States,residing at Kenosha, in the county of Kenosha and State of Wisconsin,have invented certain new and useful Improvements in Machines for MakingCoiledlVire Fabric; and I do hereby declare the following to be a full,clear, and eXact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being bad to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

My invention relates particularly to machines for the manufacture ofsuch coiledwire fabrics as are used in the manufacture of woven-wirebed-bottoms. With such machines the coils are formed by pushing the wirethrough a spiral die, and the fabric is formed by rotating andprogressing the new coil longitudinally, so as to cause it to intertwineat each rotation with the last preceding coil, and my invention isspecially though not exclusively adapted to embodiment in automaticmachines for the making of such fabrics.

The first and chief object of my invention is to meet the commercialdemands for a more rapid machine than those heretofore in use in thisart.

A second object of my invention and one that is attained incidentallywith the attainment of the first is the greater uniformity in theproduct of the machine and the reduction of waste of wire.

A third object of my invention is the produotion of a machine requiringa minimum of skilled attendance.

For commercial reasons it is desirable to operate such machines at arelatively high speed. Such high speed has long been sought. This isattested by the history of experiments in various factories and by theprior patents relating to this art. Heretofore such machines have not indaily practice woven more than thirty-five fabrics of average size in aday of ten hours. \Vith machines embodying the improvements set forth inthis application Serial No. 73,561. (No model.)

and the improvements described by me in two other applications eightysuch fabrics per day of ten hours have been and are being woven in dailypractice and with less trouble than heretofore, and I believe that aproportionate share of said increase of production is due to theimprovement herein described. The machine is now operated at a higherrate of speed, and the stops due to defective operation are now lessfrequent and of shorter duration.

The abovementioned objects are attained in part by means for temporarilypositively keeping the last fabric coil in its relative longitudinalposition when it is being out and until it has been shiftedlongitudinally in the normal manner, as hereinafter described.Heretofore such coil has been left free to shift longitudinally inresponse to tension when it was freed by the cutting-knife, excepting asit was put under restraint during formation by the mechanism along itspath. When the:

said coil is unrestrained, there is always some accidental longitudinalshifting when. the coil is out, sometimes to the extent of severalinches. When the final coil thus shifts longitudinally to the extent of,for example, two inches, then at one end margin of the fabric that muchof the coil is lacking to make the margin even and at the opposite endthat much of the coil goes beyond what is needed to make the margineven. Ifsimilar unevenness occurs occasionally as the fabric is formed,pains must be taken to push all the coils longitudinally one way or theotheruntil the margins are even. This requires labor; but suchadditional labor is not the greatest annoyance arising from suchlongitudinal shifting of the coils. The marginal or new coil of thefabric is usually normally engaged by mechanism located along the pathof the incoming coil, and the weight of the fabric or an externaltension mechanism draws transversely on the last several coils, tendingto draw said marginal coil transversely away from said engagingmechanism. \Vhenever under normal action a new coil is completed, saidengaging mechanism releases the last preceding coil and transfers itsengagement to such new coil; but if such new coil does not extend to themargin of the fabric at one end then along the space not covered by saidlast coil the engaging mechanism loses its grasp upon the fabric, andalong such space the fabric is unduly drawn away from the coiling-path,so that the coil next formed is likely to come into contact with thewire of the then last coil and have its end deflected out of thecoiling-path or meet such resistance at its end as to bend or bucklelaterally between the coil-receiving mechanism and the coil-formingmechanism, so that the coil utterly fails to advance through thecoiling-path in the coil-receiving mechanism. Whether the end of theincoming coil is thus deflected or whether it thus meets resistance thenormal operation ceases and the machine must be stopped for correction.If the'last-finished coil on being cut thus shifts longitudinally thelength of only one or two turns of the coil, the abnormal action abovedescribed may result. This accidental movement of the coil hasheretofore been obviated to some extent by confining such coil closelyby mechanism along the path traversed by said coil along the margin ofthe fabric. This method has been found objectionable, for the reasonthat when the coil must traverse such a restricted path it meets so muchfrictional resistance as to frequently cause the wire to bend at oradjacent to the beginning of such path, progression in such path thenceasing and the wire issuing from the coiler going out sidewise intospace until the action of the, coiler has been stopped. Then theincomplete coil and the coiled wire so run out of said path must beremoved and thrown aside as waste. To this waste wire must be added theloss of time involved in correctingthisfaultyoperation. Ihave found thatduring the forming of the coil its path should be limited only enough tocause it to intertwine with the last-preceding coil, and I have alsofound that by grasping and holding such last coil at or near the cutterwhile it is being cut and shifted its accidental longitudinal shiftingdue to tension is practically eliminated. To such degree is thisaccomplished that the mechanism along the path to be traversed by thecoil while entering the fabric need not so limit such path as to makesuch frictional contact as will produce objectionable resistance toprogression.

In some machines a series (or a double series) of pins extend along thepath of the new coil, and the latter crosses one such pin at each turn.In the operation of such machines it has been the practice to shortenthe pitch of the coils, so as to produce a slight tension on the coilwhen the latter crosses said pins, to the end that there might be someengagement of the coil with said pins along its entire length at thetime of cutting and during the regular shifting. Making such engagementbetween the coil and said pins when sufiicient to substantially preventthe accidental longitudinal movement of the coil produces so muchfriction as to occasionally stop the progress of the coil even when themachine is being operated at a moderate speed, and when it is attemptedto operate the ma chine rapidly such resistance more frequently stopsthe progress of the coil in its path and necessitates the stopping ofthe machine to correct the work.

If provision is made for positively engaging and relatively holding thelast coil dur ing the period of cutting and shifting, said coil may begiven a relatively free path, so that resistance to its longitudinalprogression during the period of formation can be so much reduced as togreatly limit the cases of stopping of the progress of the Wire in itspath due to contact with devices along said path intended to limit orrestrict the course of said coil.

The foregoing general statement of the nature and functions of myinvention is made to aid in the ready comprehension of the de tails ofthe construction and operation, which I shall now set forth by referenceto the accompanying drawings, in which Figure 1 is a plan illustrating aportion of a machine embodying my improvement, the coil being ready forthe cutter. Fig. 2 is a similar view taken after the new coil has beensevered. Fig. 3 is a section on line 3 3 of Fig. 2. Fig. 4 is a sectionon line 4 t of Fig. 3. Fig. 5 is an enlarged transverse section of aportion of the coil-receiving mechanism. Fig. 6 is a plan of thecoil-guide. Fig. 7isa vertical section along the first portion of thecoil-receiving mechanism. Fig. 8 is a detail transverse vertical sectionadjacent to the coil-severing mechanism.

Inasmuch as the general construction of machines of this class is wellknown, I deem it unnecessary to illustrate and describe more than theparts immediately concerned with my improvement.

A is a portion of the bed or frame of the machine.

B is the portion of the coil-forming mechanism nearest thecoil-receiving mechanism. B is the coil coming from said coil-formingmechanism.

0 is a cylindric guide for directing the coil to the coil-receivingmechanism.

The coil-receiving mechanism consists of, first, a pin-bar D, having alongitudinal channel D in its upper surface and bearing in said channela longitudinal series of vertical pins D second, a knife-bar E, and,third, two horizontal pin-bars F F, bearing hori zontal transverse pinsF, the pins of each of said bars being in a horizontal plane anddirected toward the other of said bars; but the pins on one baralternate horizontally with the pins on the other bar. Said pin-bar Dand said pin-bars F F and said knife-edge bar E are arranged tosimultaneously reciprocate longitudinally a distance equal to one halfthe length of one turn of the coils each .as to stand between the turnsof the coil occupying said channel. The knife-edge bar E is located justabove the bar D and at the side of said channel D, and it supports theknife-edge E, which edge extends laterally to and normally partiallyover said channel. The wall D of said channel opposite said knife-edgeis preferably extended above the level of said knife-edge. Said bar E isarranged to periodically reciprocate transversely to its length and in ahorizontal plane through a limited space. In its normal position saidknife-edge extends sufficiently over the channel D to reduce the upperopening of the latter to less than the diameter of the coil. Anysuitable mechanism may be employed for drawing the fabric verticallyaway from said channel D. Said mechanism places the fabric undercontinuous tension, and said knife-edge and said pins F hold the marginof the fabric in said channel. This of course involves the transferenceof the engagement of said pins and knife-edge from one coil to anotheras more coils are added to the fabric. The relation between the depth ofsaid channel and the height of the knife-edge E and the elevation of thepins F is such as that when the coilreceiving mechanism is receiving acoil the last-finished coil is pressed downward by the knife-edge E, sothat it almost touches the bottom of the channel D, and saidlast'finished coil and the last preceding coil are lowered a little outof engagement with the set of pins F then extending over said channel.v

' The new or incoming coil runs on the bottom of said channel, and thusclears the knifeedge. At each turn the wire of said coil passes betweentwo of the vertical pins D and crosses one of the turns of the finishedcoil then res ting in said channel. When the new coil has been completedand cut, the knife-edge moves horizontally away from the coilssufficiently to make the opening of said channel large enough to allowthe last preceding coil to rise out of said channel when otherwise freeto do so; but when said coil rises it first comes into engagement withthe set of pins F then extending over said channel. Then said pinsrecede from the fabric and release said coil. At the same time the otherset of pins F move over said channel in time to engage the coil nextbelow the one just released. During the interval required for thisshifting of the'engagement of the pins F said bar D, bars F F, and theknifebar E normally move lengthwise a distance equal to half a turn ofone of the coils of the fabric. This movement is made in order to takethe last-finished coil out of the path for the incoming coil. Thesehorizontal movements of said bars alternate in direction.

All the mechanism and operations thus far described are old, as will beascertained by examination of the patents to which reference has alreadybeen herein made, and said mechanism and operations are herein describedonly for the purpose of showing the application of my improvement. I

The coil-guide C is mounted upon a base 0, and said base is seated in aplate H, and said plate in turn rests upon a chair I, and said chairrests upon the upper face of the bedplate A of the machine. The spiralpath of the coil extends through said guide and emerges from thelatterat C at the beginning of the coil-receiving channel immediately infront of the upper knife G. The lower coilcutting knife 0 extends upwardthrough the plate H and the base 0'' to the point C and is adjustablyand removably secured by a setscrew G I G is the upper knife. This issuitably secured to the knife-arm G, which is hinged on the verticalheaded wrist G extending through the aperture 0 Fig. 6, in the base Ginto the plate H. The knife-arm is vibrated by the longitudinalreciprocation of a shaft G with which said knife-lever is connected byapin G extending upward from said shaft into a slot G in said knife-arm.The movement of said knife-arm is so timed as to drive the knife G pastthe point C when the new coil has been formed and the coiling mechanismhas been stopped, so that the coil is no longer advancing, and theknife-lever is then returned to its normal position before the coilingmechanism is again set into operation to drive forward a new coil. Theknifearm and the coil-guide thus briefly described are also old in theart of wire-coiling and for that reason are not specifically describedherein.

As briefly set forth in the introduction to this specification, myimprovement relates to means for engaging and holding the new coilbefore it is cut and until it is engaged transversely to its length bythe last preceding coil of the fabric, such latter engagement producingsufficient frictional resistance to prevent objectionable longitudinalmovement of the last coil when it is freed by cutting. The mechanismwhich I employ for this purpose engages the coil adjacent to the saidknife G and at the side thereof opposite the coil-guide. The end of thecoil adjacent to this point is to be kept from longitudinal movementwhatever the position of the opposite end of the coil may bethat is tosay, whether the opposite end of the coil may or may not be accuratelyin line with the adjacent end margin of the fabric the cutting-point isin line with the margin at that end of the fabric, and if the coil isalways held adjacent to said point said end margin of the fabricnecessarily becomes even. As has already been suggested, it sometimeshappens that the oppo- I siteend of the coil (the end away from thecutting-point) is vout of position, because of resistance met in thecoiling-path, so that the coil becomes more or less compressedlengthwise. If the coil is then cut so as to free the end adjacent tothe cutter, the coil will, if it is not grasped, expand and move in thedirection of the coiling mechanism; but by holding the coil adjacent tothe point of cutting until the out has been made and the coil-shiftingmechanism is set into operation the opposite end of the coil becomesfreed from the restraint which caused its compression, and it may thenexpand in the direction opposite the coiling mechanism and assume itsproper position in line with the adjacent end margin of the fabric. Thiswill be better appreciated if it is remembered that at the verybeginning'of the shifting operation the last preceding coil is raised soas to engage and lift the new coil, the last preceding coil makingcontact with the new coil at every turn or convolution. This makespoints of frictional resistance equaling in number the number ofconvolutions in the coils. The aggregate of this frictional resistanceis sufficient to practically prevent the longitudinal thrust orpropulsion of the last-com pleted coil when the latter is freed, so asto expand when it has been compressed or when it is freed, so as tocontract when it has been expanded while being driven along thecoil-path.

As statediu the introduction to this specification, it is desirable thatthe coil-path afford the greatest freedom to the ingoing coil consistentwith reliable intertwining of said coil with the last preceding coil inorder to reduce the resistance to the progress of the wire as it isdriven forward by the coiling mechanism. Such resistance must not besufficient to cause the wire to bend laterally between the coil-guide andthe coiling mechanism or in the coil-receiving mechanism; but when thecoil-path affords such freedom there is more freedom for the coil tomove endwise when it is freed by cutting, such movement being in onedirection or=the other, as the coil may have become slightly compressedor expanded during its formation,and even when the coil is not understrain the coil-severing knife tends to drive the coil endwise away fromthe cutting-point. It has heretofore been attempted to overcome thisendwise movement of the coil by making its pitch sufficiently short torequire the advancing end of the coil to slightly engage each pin D andslightly draw on the latter at the point of crossing, thus placing eachturn of the coil when completed into slight engagement with the adjacentpin D While this has proven more or less effective in preventing theaccidental endwise movement of the coil, it at the same time added somuch resistance to the progress of the coil while being driven forwardby the coiling mechanism as to cause the wire to bend laterally betweenthe coilguide and the coiling mechanism or in the coil-receivingmechanism and altogether stop the progress of the coil in the properpath. In former practice this has occurred to an objectionable degreeeven when the machine was operated at moderate speed, and when it hasbeen attempted to operate the machine at a higher speed the frictionalresistance has increased so much as to utterly prevent normal action.

The vital part of my improvement is a member which stands normallyadjacent to the coil-path near the cutting-point and is ready to moveinto contact with the coil and press it against the adjacent wall of thecoil-guide or any similar surface or otherwise suitably engage saidcoil. This member may ob viously be made in a Variety of forms. Itmight, for example, consist of two opposing jaws adapted to grasp thewire between them. In the accompanying drawings it is shown in the formof an elongated bar or finger J. Said finger is hinged upon the verticalheaded wrist J, which is fixed upon the plate J Said plate is boltedupon a reciprocatory bar J which rests in the channel 1, formed in theupper face of the chair I, transversely to the coil-receiving channel.Said bar J extends beneath the stationary plate H and almost to theshaft G Upon said bar J near the shaft G is fixed a lug J. To the shaftG3 is secured a block J extending over the adjacent portion of said barJ and having on its lower face a channel j into which the lug J extends.Said channel is mainly parallel to the shaft G but it has a horizontaloblique offset jflwhereby the lug J and the bar J are recipro catedlengthwise of the channel I when the shaft G and the block J arereciprocated, the line of the latter reciprocation being perpendicularto the reciprocation of said bar J S uch reciprocation of said barcauses the reciprocation of the plate J and the finger J toward and fromthe coil-path, as will be obvious from an inspection of the drawings. InFig. 1 said finger is at one limit and in Fig. 2 at the other limit ofsuch reciprocation. In addition to such reciprocation said finger isarranged to partially rotate in a horizontal plane, with the wrist J foran axis. During the operation of the machine said finger assumes atdifferent times three diiferent positions within said range of movement,as will be hereinafter described. A spring J attached by one end to arelatively fixed point on the plate J and by the other to said finger,tends to draw the latter to its limit next the cutting mechanism. A barI extends across the chair I at the side of the plate J opposite thecoil-guide and is suitably secured to said chair, as by screws I 1 Atthe end next the finger J said bar is extended beyond said chair, and asetbolt I extends transversely and horizontally through said bar inproper position to abut against a shoulder J on the fingerJ when thelatter approaches the adjacent limit of its movement. Said shoulder J 7is at the side of the hinge of said finger toward the coil-guide,

and it follows that the finger is turned away from the said coil-guidewhen the bar J carries the finger to its limit away from the coilpath.The set-bolt 1 is to be adjusted to cause the turning of said fingerprecisely to its intermediate position. Said spring J constitutes ayielding means for moving said fingerinoppositiontosaidset-bolt.Ontheedge of said finger toward the bar J about midway between its ends,is a lateral extension J Opposite said extension and in the samehorizontal plane an arm J is hinged upon a vertical axis at J andextends from said hinge to said finger. A suitable spring is employed toturn the free end of the arm J toward the coilpath. In the drawings thespring J (which also controls the finger J) is attached by its endopposite the finger J to a stud j, seated on the arm J". The length ofsaid arm is such as to cause it to abut against the edge of said fingerat the side of said extension to the extension J ward the hinge of saidfinger when the latter is in its position nearest the coil-guide, andthe extension J is sufficient to abut against the free end of the arm Jwhen the finger is in its intermediate position. The intermediate of thesaid three positions of the finger J assumed by rotation on the wrist J(which position is shown by solid lines in Fig. 1) may be termed thenormal position of said finger, for this is the position of rest, theposition occupied while the coil-receiving mechanism and thecoil-cutting mechanism are at rest and the coil-forming mechanismisdriving the coil forward into the coil-channel. Said position may alsobe regarded as the first of said three positions. Said finger is putinto this position by the movement of the bar J to the right, bringingthe shoulderJ ofsaid finger into contact with the set-bolt 1 wherebysaid bolt causes said finger to turn away from the coil-guidesufficiently to allow the free end of the arm J to slip over theextension J toward the coil-path. Said set-bolt is so adjusted as toturn said finger no farther than just described, and the spring J holdssaid finger against the end of the arm J From the plate H a rigid fingerH extends laterally toward the arm J a sufficient distance to abutagainst said arm when said finger J is in its first or normal position.The spring J, attached to said arm J may be termed a yielding means formoving said arm J in opposition to said rigid finger I-I. Assuming nowthat the new coil has been completed and it is to be shifted the lengthof a halfturn toward the coiler when the coil has been cut, then the barJ moves toward the left, carrying with it the plate J the finger J, andthe arm J", the shoulder J moving away from the set-bolt 1 so that thefinger J will be free to turn toward the coilguide in response to thestress of the spring J when the arm J becomes removed from Since thesaid arm J abuts against the rigid finger H, mounted on the stationaryplate H, the advancement of the plate J will cause the turning of thearm J" on its axis, such turning being to the right, until the end ofsaid arm slips clear of the extension J This latter step is so timedthat it occurs when the finger J has moved so far to the left that itextends across the coil-receiving channel. When thus freed from said armJ", said finger turns horizontally toward the coil-guide and against thecoil. The lower face of the end of said finger is low enough to beardown closely upon the coil, as well as to bear laterally against saidcoil. This is termed the second position of said finger. Said fingerthen remains stationary until the pin-bars D and F F have movedlongitudinally toward the coil-guide and'until the said bars F F haveshifted horizontally, so as to transfer engagement from one coil of thefabric to the next lower coil. Then the bar J again moves to the'right,and the finger J is again set into its normal or first position bycoming into contact with the screw-bolt 1 the arm J being again drawninto place against the extension J In Fig. 2 the operation last-abovedescribed is shown so far completed that the time has come for the bar Jto shift to the right and carry with it the plate J and the finger J.

Bot-h Fig. 1 and Fig. 2 show on the righthand pin-bar F a hook F whichis directed horizontallyaway from the coil-path. On the upper face ofthe finger J is an upright studj. With the pin-bars in their positionaway from the coil-guide the hook F just clears the stud j, when thelatter is carried to the left by the movement of said finger in thatdirection; but when said pin-bars are in their position toward thecoil-guide, as shown in Fig. 2,then the hook F is on the other side ofthe path of the stud j, so that when the finger and said stud have movedto their limit toward the left and the pin-bars F then shift to theright the studj is in the path of said hook when the time comes foragain shifting the pin-bars longitudinally away from the coil-guide.When said bars are then so shifted longitudinally, said hook engagessaid stud and carries said finger simultaneously with said bars awayfrom the coilguide to and beyond the normal or first position of saidfinger, as indicated by the dotted lines in Fig. 1. Thus the thirdposition of said finger is attained, and said position then continuesuntil said finger J and said studj are carried far enough to the rightto cause said stud to slip out of engagement with the hook F The arm Jhas by that time assumed its normal position and the extension J thenabuts against the end of said arm. Thus said finger again assumesitsfirst or normal position. After the next coil has been formed the shiftof the finger J is again to its second position-namely, across thecoil-channel and toward the coil-guide. Then it again shifts to thenormal position. Then it again goes to the second position and from thatto the third position and thence to the first position. The movementfrom the first position is always to the second, and from the secondposition the movement is alternately directly to the first position andto the first position by way of the third position; but the aforesaidalternation ceases when coils are to be manifolded to form cords atintervals in the fabric. Then the movement is direct between the firstand second positions until the cord has been completed. Such cording isan old procesS in this art. In automatic machines of this class this isaccomplished by suspending the action of the fabric-shifting mechanismduring the formation and cutting of as manycoils as it is desired to putinto a cord. Mechanism for effecting such suspension is described in thepatents already herein mentioned.
